The common brown centipede, Lithobius jorJcatus (L.), releases a sex‐specific pheromone which emanates from distinctive cuticular openings on the coxae of the hind legs‐the coxal pores (Littlewood & Blower, 1987). The pheromone can be isolated from tissue extracts of the coxal organs (surrounding the coxal pores) and from substrata which have been 'marked by male or female L. forjcatus and presented to centipedes in the form of a behavioural bio‐assay. In this paper, further evidence is presented for a centipede pheromone, the chemical components of male and female secretions are separated using Gas Layer Chromatography (GLC), a qualitative chemical analysis is described and the nature of the pheromone is discussed.
